For the first time in the history of science, researchers have captured fascinating images showing an octopus using its siphon to fling stones and shells towards fish. This behavior, observed in the octopus called coconut octopus (Amphioctopus marginatus), marks a major and completely new step in the understanding of these marine creatures with their impressive cognitive capacities.
In these images, shot on a coral reef in Australia, the octopus deliberately manipulates fragments of shells or sediment using its tentacles, before propelling them at high speed using its siphon. An almost surgical precision that leaves experts amazed.
A sophisticated defense or inter-species rivalry?
Why do these octopuses behave like this? Several hypotheses are emerging among marine biologists. One possibility is that these jets serve to ward off overly intrusive fish or to mark their territory in these crowded ecosystems.
But this behavior could also reveal a form of direct competition between species, octopuses thus asserting their domination over coveted areas. It is not just a matter of reacting to immediate danger, but of demonstrating a proactive strategy, a rare characteristic among invertebrates.
Octopuses are already famous for their intelligence, adaptability and ability to use tools. This new example reinforces the idea that they are among the most intelligent animals in the ocean, capable of complex social behaviors and strategic decision-making.
What these images reveal about octopus intelligence
These new images overturn preconceived ideas about the capabilities of invertebrates, opening a new window on the intelligence of octopuses. Throwing stones and shellsfilmed for the first time, demonstrates an ability to plan actions and actively interact with their environment.
Octopuses were already known for their ability to solve puzzles, camouflage themselves in sophisticated ways, and even manipulate objects such as coconuts for protection. This new behavior suggests that they are not just reacting to their environment but actively influencing it.
Comparisons have already been made with other animal species, such as certain birds or primates capable of using tools. However, in octopuses, this proactive action is particularly intriguing, as it is observed in animals without complex social structures, unlike mammals or birds.
This animal has three hearts, how is this possible?
Towards new research and broader implications
This behavior raises exciting questions for marine biologists: How can a creature without a spine or cerebral cortex develop such skills? Do octopuses have a form of social intelligence or simply a very sharp instinct?
From a practical point of view, these observations could influence research in robotics or artificial intelligence. The flexibility and adaptability of octopuses are already inspiring innovations in engineering. With this new example of active manipulation of their environment, they could offer new models for the creation of intelligent systems.
Furthermore, these discoveries highlight the importance of protecting marine habitats. Each new behavior observed shows that thousands of secrets of marine life remain to be discovered, reinforcing the urgency of preserving these threatened ecosystems.
Summary in 5 points:
- An octopus filmed for the first time throwing stones and shells to defend itself.
- A rare ability among invertebrates, comparable to the use of tools.
- This behavior demonstrates proactive and not reactive intelligence.
- Potential implications for research in marine biology, robotics and artificial intelligence.
- A discovery which reminds us of the urgency of protecting marine ecosystems.
